Compiler complains over default png filename created

[ArchOwlen]

Compiler Error: Axolotl.fnt should either have matching image table png/gif or encoded image data in the file

Does not work (default settings):

Works (edited out ".fnt" in png name):

Command Used:

This is probably just user error, but may be useful for others struggling to figure out what went wrong
